A snippet of conversation from my darling offspring a few minutes ago:

McDonald's toilet cubicle #1:
"My beard is black,
There's soot in my sack,
My nose is tickly tooo!"

Cubicle #2:
"Grrrrr!!!"

Me, hovering self-consciously at ladies' toilet door:
"What?? What's wrong?"

Cubicle #2:
"I hate that song!"
